JSF :: Column Added In ForEach Tag Not Displaying
Nov 4, 2014
I have a ace:dataTable which contains a variable number of columns. For this I use the c:forEach tag. All generated in the c:forEach are not displayed. In the sample, only columnLibelle and columnSum are displayed.

I am trying to access an array of "Movie" objects in my jsp. The array is loaded via
org.springframework.web.servlet.ModelAndView.addObject().
Here is my jsp code:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="security" uri="http://www.springframework.org/security/tags"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
[Code] .....
The System.out.println("jsp page: .... &> results in the output: "jsp page: movielist - [Title: Die Hard; Budget: 20000000, Title: two days in paris; Budget: 1000000]" so I am confident the objects are being loaded into the ModelAndView correctly. However the output of the block is "${movie.name}" instead of the list of movies. My movie object has a getName() method to return a string (and a setName() method). I am not sure why the System.out.println statement can find the movielist attribute, but ${movie.name} is being treated a plain text. There are no execptions thrown or other indications of errors.

I've implemented Stack on the base of the LinkedList. It works as i expect it to work, but then i tried to made it compatible with foreach loop. I've implemented Iterable and Iterator. Code compiles and works fine, but does not return any output. It looks like while working with foreach, next() is not called at all. If i`m getting iterator from instance and try to do iterator.next(), i get output as expected.
public class genericStack<T> implements Iterator<T>, Iterable<T> {
private LinkedList<T> LL ;
protected genericStack() {
this.LL = new LinkedList<T>();
}
public static void main(String[] args) {

I am trying to use an iterator instead of a foreach loop to go through a list of inventories to see if a car is rearDrive and count how many are rearDrive but somehow I seem to be missing something that the counter isn't working as expected.
public int howManyAreRearWheelDrive(){
int i = 0;
int counter = 0;
int inventSize = inventory.size()-1;
while(i < inventSize){
boolean wheelDrive = inventory.get(i).getIsRearWheelDrive();
if( wheelDrive == true){
counter++;
}
}
return counter; // returning here doesn't give me anything
}

I am creating a .jar for a game I made. I'm not using any dev tools, just a DOS console call to java: %~dp0....javajdkinjar.exe -cfmv TheSwarm.jar manifest.txt *
My manifext.txt contains:
Main-Class: Game
But when I compile the jar, its manifest contains:
Manifest-Version: 1.0
Created-By: 1.7.0_01 (Oracle Corporation)
And I get an error about it not finding the main class. Shouldn't my Main-Class setting be added to the jar? I can manually rename it to .zip and edit the Manifest.MF but that is a huge pain when I'm testing the .jar file and regenerating it often.

I'm just a java beginner. I've spent a lot of time installing and configuring software. I'm using Netbeans 7.3 on Windows 7, 64 bit. Recently, I downloaded opencsv from sourceforge.
With no previous experience adding libraries, I read a blog post on adding the library. I think that I then:
Start a new project.
Right click on libraries
Add jar/folder
Gave the temporary path to the .jar file
After, I read the blog post again, and realized I'd missed it. This time I did:
Right click library, Add library, Create library
However, I kept getting a message that the same library already existed. If I do the first process above, I will find the same library.
However, I see no way in Netbeans to remove it. I've deleted the test projects. And started a new one. But the library now exists for all projects it seems.
I've grepped all the files under the Netbean directory, searching for "opencsv", but found nothing. The only things in the Windows registry were locations of files.
How can I delete this library permanently from Netbeans? Short of, uninstall, then reinstall? Is there a way to list all the libraries that Netbeans has?

The following alert returns an added string instead of adding the var together to give me a total?
var tvHours = prompt('How many hours of Tv do you watch last week?');
var webHours = prompt('How many hours of internet surfing did you do last week?');
var gameHours = prompt('How many hours of video games did you play last week?');
alert(tvHours + webHours + gameHours);
Also can you store a var in an alert? e.g ( var time = alert(tvHours + webHours + gameHours); ???

I have a .jar that is installed in other computer(outside netbeans). Everything works fine except with report. I am sure the libraries needed for iReport is added in my lib folder but I receive this error message when I to load the report using the program.I use command prompt to see the error:

I am adding JLabels to my JPanel, and the last one always does not show up. For example if I add 3 JLabels, the 3rd will not show up. If i change it to add 4, the 4th will not show up, but the 3rd will now. Here is a snipit of what my code looks like:
setLayout(new BorderLayout());
for(int x=0; x<PEDALCOUNT; x++)
{
pedals[x].setBounds((x*PEDALWIDTH),0,PEDALWIDTH,PEDALHEIGHT );
add(pedals[x]);
}
A workaround that I DO NOT want to keep doing is to put an extra fake JLabel at the end of the for loop, that way everything I want to show up does, but the fake one does not.

In the code below, under calculations, I have x=totalPrice+xXxXxX. Obviously the x's were just place holders, but I wanted to know if there was any way to add something there so the program would tally the totalPrice, store it in the x variable outside the loop, so when the loop ended it would display the total price from all the loops added together where I have System.out.println("TOTAL OF ALL ORDERS: $"+ round.format(x)); at the very end.
Java Code:
import java.util.Scanner;
import java.text.DecimalFormat;
public class ModifyOrderV2TEST
{
public static void main(String [] args)
{
//Rounding
DecimalFormat round = new DecimalFormat("0.00");

I'm trying to develop a system for test cases so that whenever a test case is added to a particular package it will automatically be included in testing without having to manually add that particular test case. What is the best way to achieve this? Should I use java reflection? I'm just getting started with Jenkins and trying to configure Selenium test cases.

I have a JPanel that's using a simple GridBagLayout.
JPanel panel = new JPanel();
GridBagLayout qPanelLayout = new GridBagLayout();
qPanelLayout.columnWidths = new int[] { 0 };
qPanelLayout.rowHeights = new int[] { 0 };
qPanelLayout.columnWeights = new double[] { Double.MIN_VALUE };
qPanelLayout.rowWeights = new double[] { 0.0 };
panel.setLayout(qPanelLayout);
componentCount = 0;
Based on user input I am adding sub-panels to the panel. These sub-panels may vary in height. They take up the full width of the Panel.
public void add(Component comp) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.insets = new Insets(2,2,2,2);
gbc.gridx = 0;
gbc.gridy = componentCount++;
panel.add(comp, gbc_questionPane1);
}
The odd behaviour I'm seeing is that if the height of the new sub-panel I'm adding is less than the height of the largest sub-panel currently displayed then the main panel does not repaint. If its height is equal or greater then the Panel does repaint, and any sub-panels that were added but not visible before are now painted. What have I missed?

how can i get id from db table for each column values with java or oracle query? i did get before each column content from file and now i need get the id of this column values from db. I read csv files from folder and then load the data from these files into subfolder, and here with line li = line.split(","); i get the values that i have in csv file and split them and become in li the value name, and then in else block i create a P objekt where i set this values from csv files, and with [I]p.setLid(li);
I set the value for all valuenames, and then get these valuenames in separate column with other content from this csv, and my question is, i need to do this with db, and write these csv file values to the table in db (it will be done with another java class), what i need, that to write the ids of these values into the table in db, instead of valuename, and while there is no ids for valuenames in csv files, i need to get the id from the table in db where these are already listed with sequences.
I don't know how can i write in data table the id of this valuenames and other content, this data table should contain the ids of valuenames timestamp values and the ids of the csv files name, i don't know how to do this with the ids, i must get the ids from the db table and then set these on [I]p.setLid(li); where i set early the valuenames, instead of valuenames i should set ids, that will set ids automatically for all these valuenames.
try {
while ((line = br.readLine()) != null) {
if (lc == 0) {
li = line.split(",");
} else {
String[] temp = line.split(",");
for (int i = 1; i < temp.length; i++) {
p = new P();
[code]....
i got the values that then will be given to [I]p.setLid(li); and iterate, but now i want to get id from the table in db where this values stored with id instead of this column values, how can i do it?
